Hi Karunya,
According to me, B.A. course is best for you. Example-Economics, policy public administration, etc. I too completed my inter with good marks. I have studied inter+civil at IAS Academy.

The JEE Mains percentile between 75 to 80 is good enough for Jamia Hamdard University for B.Tech CSE. So your chances are good enough for admission.

Admission is based on a combined merit of 50% marks in all India aptitude test (comprising of Objective Type tests in Physics, Chemistry, Mathematics (for B.Tech.)/ Biology (only for B.Pharma.), Logical Reasoning) and 50% of normalized aggregate percentage in 10+2. Therefore, the marks above 60 out of 100 are good enough for admission in B.Tech CSE.
